  • a photovoltaic device may be used at a location with a large range of temperature variation.
  • a change in temperature may cause expansion or contraction of the bottom portion, thereby changing a distance between the power generation element provided at the bottom portion and the Fresnel lens provided at the upper surface of the case.
  • side wall 24 is composed of a resin. Therefore, even if the focal distance of the lens is changed in response to the change in temperature, the side wall is also expanded or contracted in response to the change in temperature, thereby changing the distance between the lens and the power generation element.
